I've made tree-sitter parsers for bibtex and biber. I've tried to be as accurate as possible with the syntax, so the two are actually somewhat different. I figure we can add one or the other (or both). biber is probably the better choice though, because it's mostly compliant with bibtex (at least if being used reasonably), and it looks like the biblatex package is eventually dropping bibtex support anyway. I've tried to document the important differences.
